"Fuck me, you disgusting thing!" the elf girl hisses, her voice laced with a mix of revulsion and lust as she watches the slime's form shift and change, growing more human-like, more masculine. Its cock, now thick and veined, plows into her, stretching her tight elven pussy to its limits. The slime, driven by its primal desire, pounds into her, its body glowing with an ethereal light. The elf, caught in a whirlwind of taboo lust, claws at her own breasts, tweaking her nipples as the slime's tentacles snake up her body, wrapping around her throat, her wrists, pinning her down as it fucks her harder, faster, filling her with its alien cum.
